Third Embodiment
[Device configuration]
FIG. 9 is a diagram showing an example of a hydrogen-containing gas supply system according to a third embodiment.

In the example illustrated in FIG. 9, the hydrogen-containing gas supply system 100 includes a hydrogen-containing gas generator 1, a hydrogen-containing gas supply device 2, an acquisition device 13, and a controller 5. The hydrogen-containing gas supply device 2 is the same as that of the first embodiment, so the description thereof is omitted.

The hydrogen-containing gas generator 1 is a device that generates a hydrogen-containing gas. The hydrogen-containing gas generator 1 may have any configuration as long as it can generate a hydrogen-containing gas.

For example, to the hydrogen-containing gas generator 1 of FIG. 9, an air supply path 6 for taking in air from the atmosphere and a hydrogen supply path 9 for taking in hydrogen from a hydrogen source are connected. Then, the hydrogen-containing gas generator 1 can generate a hydrogen-containing gas having a desired hydrogen concentration by mixing the hydrogen from the hydrogen supply passage 9 and the air from the air supply passage 6 at a predetermined mixing ratio. . The hydrogen-containing gas generated by the hydrogen-containing gas generator 1 is supplied to the hydrogen-containing gas supply device 2 through the hydrogen-containing gas supply passage 8.

The hydrogen-containing gas generator 1 may include a buffer tank (not shown) for stabilizing the supply amount of the hydrogen-containing gas. As said hydrogen source, although the electrolyzer of water etc. can be mentioned, for example, it is not limited to this. Further, as described above, in the hydrogen-containing gas generator 1, oxygen gas or nitrogen gas and hydrogen may be mixed instead of air.

The acquisition device 13 is a device that further acquires biological information of a person present in the area 4. Here, for example, the body temperature can be cited as human's biological information.

For example, an infrared sensor can be used as such an acquisition device 13. That is, the infrared sensor can detect the body temperature as the biological information of the person in addition to the presence or absence of the person in the area 4.

The acquisition device 13 may be the same as the acquisition device 3A of the first embodiment except for the above points.

The controller 5 controls the hydrogen concentration of the hydrogen-containing gas generated by the hydrogen-containing gas generator 1 based on the biological information of the person acquired by the acquisition device 13. For example, each of the air supply path 6 and the hydrogen supply path 9 is provided with a flow rate regulator (not shown) for adjusting the air flow rate and a flow rate regulator (not shown) for adjusting the hydrogen flow rate. The hydrogen concentration of the hydrogen-containing gas generated by the hydrogen-containing gas generator 1 may be controlled by controlling the operation of the flow regulator.

The hydrogen concentration in the hydrogen-containing gas flowing through the hydrogen-containing gas supply passage 8 may be set to a value below about 4%, which is the flammability limit of hydrogen, in consideration of the stable operation of the hydrogen-containing gas supply system 100. However, depending on the situation, it may be set to 4% or more according to the operating situation and installation environment of the hydrogen-containing gas supply system 100. For example, when it is desired to quickly increase the concentration of hydrogen in the area, the concentration of hydrogen in the hydrogen-containing gas at the outlet of the hydrogen gas feeder 2 can be set to about 4% or more. In this case, even if the hydrogen concentration in the hydrogen-containing gas is approximately 4% or more, the hydrogen flowing from the hydrogen-containing gas supply device 2 into the area 4 is rapidly diluted by the air present in the area 4 In some cases, the stable operation of the hydrogen-containing gas supply system 100 may not be impeded.

[Operation]

The following operation may be performed by the control circuit of the controller 5 from the storage circuit by the control program. However, performing the following operations by the controller 5 is not necessarily essential. The operator may perform some or all of the operations.

Steps S1, S2, and S3 in FIG. 10 are the same as steps S1, S2, and S3 in FIG.

When it is determined from the information acquired by the acquisition unit 13 that a person is present in the area 4 (in the case of “Yes” in step S1), the acquisition unit 13 further acquires biological information (for example, body temperature) of the person ( Step S12).

Next, in step S13, based on the biological information acquired in step S12, the hydrogen concentration of the hydrogen-containing gas generated by the hydrogen-containing gas generator 1 so that the mixing ratio of hydrogen and air becomes a predetermined value. Is controlled. And hydrogen content gas is supplied to area 4 from hydrogen content gas supply machine 2 at Step S2.

On the other hand, when it is determined from the information acquired by the acquiring device 3 that there is no person in the area 4 (in the case of “No” in step S1), the supply of the hydrogen-containing gas from the hydrogen-containing gas supply device 2 to the area 4 Is stopped (step S3).

For example, it is assumed that the higher the body temperature as biological information, the more the production of active oxygen and free radicals in the body. Therefore, in this case, the amount of hydrogen taken into the body can be increased by increasing the hydrogen concentration of the hydrogen-containing gas supplied from the hydrogen-containing gas supply device 2 to the area 4. This can enhance the reduction effect of hydrogen on active oxygen and free radicals in the body.

When the body temperature is low, for example, as in sleep, a situation in which the amount of activity is low and the generation of active oxygen and free radicals in the body is low is assumed. Therefore, in this case, by reducing the hydrogen concentration of the hydrogen-containing gas supplied from the hydrogen-containing gas supply device 2 to the area 4, it is possible to suppress an increase in the amount of hydrogen in the hydrogen-containing gas.

The hydrogen-containing gas supply system 100 according to this embodiment has the first embodiment, the example of the first embodiment, the second embodiment, and the first modification to the second modification of the second embodiment, except for the above-described features.

For example, it is assumed that the higher the body temperature as biological information, the more the production of active oxygen and free radicals in the body. Therefore, in this case, the amount of hydrogen taken into the body can be increased by increasing at least one of the supply flow rate and the supply flow rate of the hydrogen-containing gas supplied from the hydrogen-containing gas supply device 2 to the area 4. This can enhance the reduction effect of hydrogen on active oxygen and free radicals in the body.

When the body temperature is low, for example, as in sleep, a situation in which the amount of activity is low and the generation of active oxygen and free radicals in the body is low is assumed. Therefore, in this case, the amount of hydrogen-containing gas supplied from the hydrogen-containing gas supply device 2 to the area 4 can be reduced to suppress an increase in the amount of hydrogen-containing gas.
